What speaker impedance setting do I use on my new yamaha r-n800a receiver for my elac dbr62 bookshelf speakers?
The yamaha manual says this about setting impedance:
------------------------------------------------------------------
4 ohm MIN For speakers with an impedance of 4-ohm or more but less than 8-ohm.
8 ohm MIN For speakers with an impedance of 8-ohm.
------------------------------------------------------------------
The bookshelf speaker manual says nominal impedance is 6 ohm, but on the back of the speaker it says: Suitable for Amplifiers: 4 - 8 ohms Nominal Impedance: 6 ohms Max Power Input: 120 watts
So which setting on the yamaha do I use and what are the consequences of each?

First, congrats on the rn800a and the dbr62's, that's one fine setup. What you have there is basically a limiting switch. I'm not big on them b/c they limit the power. Take Chrispy's advice and don't crank the amp.

Thanks everyone! The article that Chrispy linked was very informative. I am leaving it set at 8 ohms.

Also as an FYI, I tried the S.M.S.L AO200 MkII as a desktop amp to power these speakers (I have them for my computer), but it wasn't powerful enough to drive them without clipping more than around 78 db at 3 feet! The yamaha I have now is working wonders and seems to have all the power they need.
